This study examines the impact of transformation-oriented behavioral accounting on business sustainability within Baghdad’s State Company for Textile and Leather. The study employed a qualitative approach and an interpretative phenomenological method. The statistical population consisted of the managers of the Baghdad Textile and Leather Company. From this population, 14 individuals with their knowledge of accounting and behaviorism were selected through purposive sampling. Sampling continued until data saturation was reached. The data were collected using semi-structured in-depth interviews. The interview analysis yielded one main theme: transforming the financial decision-making model into a sustainability model through behavioral accounting. This theme was further elaborated upon in nine sub-themes, including: the necessity of transitioning to sustainability in the face of competitive market challenges; facilitating sustainable transformation; the impact of organizational culture; behavioral accounting, financial responsibility, and management; improving sustainability reporting; enhancing strategic decision-making for sustainability; improving stakeholder engagement in sustainability; improving environmental performance; and improving social performance. Identifying these themes not only increases insight and awareness regarding behavioral accounting geared towards transformation and sustainability but also demonstrates that behavioral accounting is a dual-track approach with positive implications for both the behavioral and accounting dimensions of a company. It can offer potential benefits to Baghdad Textile and Leather Company.
